Recommended Exercises Before Tummy Tuck?

It is great that you are embarking on a weight loss/health program before tummy tuck surgery. Being in good overall shape will help with your recovery. Make sure you are eating plenty of protein. Losing weight can lead to nutritional deficiencies and you need to be well nourished to heal a surgical wound. Aerobic exercise will help you lose weight and improve your heart and lung health. Be cautious about trying to do heavy abdominal exercises before the surgery as this may worsen rectus diastasis ( the muscle separation that is repaired during the tummy tuck).

A healthy well balanced diet with nutritional supplements and added Vitamin C is excellent. Avoidance of smoking for 4 weeks is essential. I strongly encourage patients to consider a Pilates style regimen of core strengthening exercise after surgery and embarking on the proper routine pre-operatively is an excellent idea.

You are to be congratulated for your motivation to lose the weight before having a tummy tuck, since your results will be better and the surgery safer.
It doesn't really matter what type of exercise you do in terms of the recovery but there are some guidelines to keep in mind during the weight loss period. Most important is to recognize the importance of building some muscle mass rather than focusing on cardio exclusively.
Muscle burns more calories at rest and while exercising, so it gives a real boost to the whole weight loss plan. Working on the abdominal muscles may seem like a good idea but working on larger muscles like the thighs will be more useful.
